The Schedule referred todnthese Letters Patent and-making part of the stems To all whontit'may concern Be it known that I, WILLIAMH. WEEKS, of the city, county, and State of New York, have invented: a. new and useful Improvement. in .Fulminate for Lamp w icks; and I do hereby declareth'at the following is a. full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the acom'panying drawings forming part of this specification. a

-Figure 1 is a detail vertical section of myimproved device. Figure 2 is-a'detail vertical se'ct-ionofthe same, taken at right ngles to the section shownin fig. 1.

Figure 3 is side view of the wick. Figure dis an edge view of the same.

. The fulminate is placed in indentations or holes, or

in a continuous longitudinal groove in the wick; A

slighttaria-t-ioniu the ingredients of thefulndotstvwill prevent the firevfrom following the line of the fulminate down into the wiek tube. My invention relates to fr lminate's for lamp-wicks, and consists in a new composition of matter, whose iizgredients will be specifically pointed out hereina er.

In order more clearly to show the mode of applyingmy invention, I ,will describe the mechanical. means which I preferably employ. Ais the body of the burner, which is screwed into. the mouth or cap of the lamp or the taper reservoir, in the ordinary manner, and to which is attached a wick-tube, B. p

,G are the spur-wheels, by which the wick is raised and lowered, and which work -'through slots in the tube B.

The spur-wheels C are attached to-the shaft D E, which is made in two parts.

The part .D of the shaft, to which the spur-wheels O" are attached, has arsquare hole formed through it, to receive the squared inner end 'of the other part E of said shaft, totc outer end of which part is at tachedthe but-ton y. which the shaft is operated.

Upon the inner end of the part-D of the shaft D E revolves loosely a disk or wheel, F, having two cams oi inclined flanges formed upon it, which rest against 'the stop-pins G attached to the upper and lower parts of the body A. I The cam-wheel 1: is held forward against the stoppins G by a coiled spring, 15!, c'oiled around the part D of the shaft D E, one end of the said spring resting against the said cam-wheel F, and the other end v against one of the spur-wheels O.

w To the part E of the shaft '1) E. is attached, or

upon it is formed, across-bar. l. which, when the of the cam-wheel F, so that, when th said part .of the shaft is; revolved to turn 'up the wick, the end of the cross-bar I may strike against a stop-pin-,-Ji.at-' tachcdto the face of the-cam-wheel '15, so that the'cam-wheel will rho turned with and by the' said 'volved back by the spring K.

.Qne' end-of the spring Klis attached to the body A, and its other end presses against the lower end of. the, leverL. I v.

,The lower end of the lever L is connected witlrthe cam-wheel If by the connecting-rod, M, one end of which is connected with the said cam wheel, and the otherend with the end ofthe said lerer' L.

The lever L is pivoted to the body A,and its up.- per end is turned inward, formed into a point, and so arranged that, when the cam-wlleel'is released, the

'upper end of the lever L will be. thrown forward to pass through a notch in the upper edge of the wick? tube B to ignite the wick.' v

- By drawing the part E of the shaft D E outward,

so that'the cross-bar I cannot come in contact with thestop-pin J of the cam-wheelF, the wick maybe turned up and down. without operating the lever L.

The wick is prepared for use as follows; An ordinary. wick is taken, andholes or indentations are formed in it at sucha distance apart that one of them may be struck at each blow of thelevei' L,

as the wick is turned up, and in suchposit-ions that they will not be struckiby the spur-wheels C.

In these holes or indentations is placed a drop of a fulminate, prepared as follows:

Acacia, three parts. I I

Amorphous phosphorus, three parts.

Sulphur, two parts.

These'ingredients are mixed in water, and one part of chlorate of potassa .is added, enough water being used to make the mixture of about the thickness of. molasses.

. If desired, the fulminate may be colored bythe admixture of one part of minium or Chinese blue, or othersuitahle coloring material.

This preparation will not, be aflected by the oil in the lamp or the wax of the taper.

The wick-tube Bis made a little larger than the wick, and a paper or other fibrous lining is inter:-

posed' between the tube and wick, so as to conducttheoil n around the wick, and guard 'aga.inst' the said her Eds pushed inwardgstrikes a inst the [ace
